Components operating in high vibration and wide operating temperature environments such, as automotive electronics, have to absorb both board flexure stress and stress from the expansion and contraction of solder joints due to thermal shock. Thereby manufactures have developed conductive soft resin-polymer as the thermo-mechanical shock absorber improving connection reliability compare to conventional electrodes. TDK has present its explanation in article below.

NASA’s Perseverance Rover recently made a successful landing on Mars, embarking on a two-year mission to seek signs of ancient life and collect samples. Because Mars is extremely cold—nighttime temperatures can drop below -112 F—heaters are required to keep the rover’s battery system from freezing. Now, researchers reporting in ACS’ Nano Letters have 3D printed porous carbon aerogels for electrodes in ultralow-temperature supercapacitors, reducing heating needs for future space and polar missions.
